Application February s, 19st,

' j (ci. 15s-128) i invention' i'r'e' 1ates to.' "a tray i attachment for chairs or' the keahd itl is primarily "an object of the. invention to` provide a device that may readily be mounted on a chair seat or the like to provide a convenientlyarranged tray for use by infants or others needing such service.

Itas an obec't ofthe-invention to provide an l attachment of this kind pro'idedmeans whereby liability ofthe occupant of the chair or the like sliding YIoff .the'refiorn substantially eliminated.

.Another object of the invention -is to provide a device s of this kind including 'a conveniently mounted backrest especially desired when the attachmentlis 'for use by an infant orwhen the seating surface is of considerable area.

This inventionalso haso'r :fan object to providea device of this kind of a knockdown type :to allow ready and convenient cleaning of 4the 's t s a'ihtaifi th'ede'v'ic'efina sani-tary vcondition andto allowv 'the device to be readily transported or stored.

The invention consists in the details of construction and in the combination andarrangement of the several parts of my improved tray attachment for chairs or the like whereby certain advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a View in side elevation of a tray attachment embodying the invention and in applied position, the associated seat being shown in fragment;

Figure 2 is a view in front elevation of the attachment unapplied;

Figure 3 is a view in top plan of the attachment as illustrated in Figure 2; and

Figure 4 is an enlarged detail sectional view taken substantially on the line 4 4 of Figure 2.

As illustrated in the accompanying drawing T denotes a tray in simulation of a crescent. However, the invention is not to be limited to any particular design, style or tray body.

The rear marginal portion of the body T in the central portion thereof is provided with an elongated shallow socket I, having its longitudinal axis transversely disposed on the tray body T. Depending from the central portion of the socket I is an elongated shank or stem 2, which extends snugly through an opening 3 midway of the ends of the substantially semi-circular member M the extremities of which provide supporting legs 4.

Serial Nor-143114 Thel central 'portions '5 of the member 'its "outer `orconvex portion provided with Va straightedge "face a, 'said portion t seating'withir'i the `socket I whereby the member 'is held against'rotat'ionaround shankorstem 2. ,l A,

, The central portion oi 'the member M in inner or Aconcave side is provided withv a i'elativeii? large recess is 'through the-contrai port-'ionbf which "the shank or stem-2 4is directed. said snani; or stem being of a leiigt'h toestond a 'materiai distance beyond the inner 'central vportion of `lthe members/'L Fitting' snugly with' the `recess -6 1icjair end portion of 'a plate i. The upper "end of the plate 1v or that portion fitting-'within 'the recess @is provided with a socket s 'iiito which snugly `rits the outer 4end "portion of the shank or stem Y The plate `1 in sideelevation increases in-width at the outer lside thereof from the top tothe botr 'toni of the plate-whereby is provided'an elongated bottom edge face b fordirect contact with-the supporting surface or seat with which the device may be employed and for which reason the ends of the member M and the edge face bl are coplanar. l

Freely extending into the upper portion of the plate 'I through the outer outwardly and downwardly inclined face c thereof, is a spring pressed latch bolt 9 which engages with a recess I0 in the outer end portion of the shank or stem 2 whereby the tray T, member M, and plate 'I are releasably locked or held in assembly.

In practice, the device is placed upon a marginal portion of a chair seat or the like and the device is held in ,place by the clamping means I I carried by and depending from the plate 1 to engage under the chair seat or the like.

While the plate 'l provides an additional support for the tray T, in practice this plate 'I is positioned between the legs of an infant and provides an effective medium to prevent the child from sliding off the seat.

The substantially crescent form of the tray T provides at the ends thereof the rearwardly disposed arms I2, the opposed faces ofwhich being .provided with the slits I2a spaced apart lengthwise of the arms I2.

The device also includes a backrest R of a ma.-

terial possessing the requisite rigidity and extending forwardly from the sides of the rest R are the elongated at and substantially rigid arms I4. The outer or free ends of the arms I4 are provided with the depending flat lugs I5. having their edges laterally disposed so that the lugs I5 may be selectively engaged within the In: Aw?- f:

. l t t.. 3 slits 12a of the arms I2 to maintain the backrest R in desired `Working position. The free extremities of the lugs I are continued by the fore reason of the convenience and facility with which it may be assembled and operated.

I claim:

1. The combination with a chair; of an attachment therefor comprising a tray structure having a rim; rearwardly directed arms in continuations of the opposite ends of the rim of the tray, a back rest attached to the free ends of said arms and adapted to rest on the seat of a chair, a supporting means beneath the tray adapted to rest on said chair seat, a plate depending from said supporting means to a substantial extent therebelow; clamping means carried by said plate and adapted to be positioned beneath said chair seat to engage the underside thereof and to hold the tray in place, the supporting means being positioned so that it is adapted to be straddled by an infant when seated on said chair seat, the back section being of arcuate form in cross section and having arms extending forwardly from its opposite Vsides for connection with the rst arms, and cooperative means connecting the last named arms with the rst arms to allow for the adjustment of the backrest relatively to the tray structure.

2.I-he combination Withan indants chair having a vseat and backofjganattachment therefor-'comprising a tray structure fhaving a rim; rearwardly Vdirectedfarr'ns in continuation of the y opposite endsv ofthe rimcf the tray,` a back rest attached ,tol the' free ends of said arms and adapted to rest on `the seat of a chair, a supportingfmeans beneath the. tray adapted to rest on said'chairiseat, a plate dependingfrom said supporting meansv to a substantialextent therebelow,

a clamping means carried by said plate and adapted to be positioned beneath said chair seat to engage the underside thereof and to hold the g.. i

tray in place, the supporting means -being' positioned so that it is adapted to be straddled by an infant when seated on said chair seat, an arcuate membernsecured at its center to the under side of the tray and having its ends resting on said chair seat-adjacent the opposite side edges thereof to prevent the infant from turning sideways on the seat, the said supporting means being secured to the arcuate member at the front center thereof.
